Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To obtain a producing method of a polymer dispersion type liquid crystal electro-optical element by which an oriented film is stably formed and display defects or decrease in contrast can be prevented by treating the surface of a electrode layer with plasma. SOLUTION: A transparent electrode 2 formed in stripes and an oriented film 3 are formed on the inner surface of a transparent substrate 1. A signal electrode 11 comprising Ta (tantalum) is formed by sputtering or the like on the inner surface of a transparent substrate 8, and the surface of the signal electrode 11 is oxidized by an anodic oxidation method or the like to form an insulating layer 12. Pixel electrodes 13 comprising Cr are formed into a desired shape by vapor deposition on the insulating layer 12. The transparent substrate 8 thus prepared is introduced into a plasma treating furnace containing oxygen to expose the substrate to oxygen plasma. By treating the surface of the pixel electrodes 13 with plasma, the surface energy of the pixel electrodes 13 changes to improve wettability for a soln.  Thereby, repelling against an oriented film 16 to be formed on the surface is prevented and the oriented film 16 can be uniformly formed in a flat state.

Abstract: PURPOSE:To obtain an elastic forming mold consisting of a stationary piece integrated to an elastic mold, by using a mold consisting of a production mold protruded from a batten, completely dipping the mold in a solution for forming an elastic material, taking the mold out of the solution and drying and solidifying the attached solution. CONSTITUTION:The objective mold for the production of ice candy, ice cream, chocolate, boiled fish paste, etc., having particular shape is constructed of a stationary piece 3 integrated to a hollow mold M made of an elastic material. A dipping mold A consisting of a production mold 2 having a shape corresponding to the hollow mold M and protruded from a batten 1 is used in the production of the objective mold. The dipping mold A is completely dipped in a solution (a) capable of forming an elastomer (e.g. latex liquid) to coat the whole surface of the mold A with a gelatinous elastic coating film. The coated mold A is taken out of the solution, solidified by drying and released from the mold. The objective mold consisting of a stationary piece 3 integrated to a hollow mold can be produced by this procedure. The same dipping mold A is being used in conventional method, however, the difference from the present process is that only the production mold 2 is dipped in the solution while keeping the batten 1 from dipping.

Title: Parallel synchronization running system
Inventor: ONO KOICHI
IPC: H04B1/74
Filed: 1985-11-05
Abstract: PURPOSE:To always obtain an output of the specified level by providing a coupling circuit receiving power from the 1st and 2nd power supply circuits to a switch, driving the switch by the 1st power supply circuit when the 2nd power supply circuit is interrupted and outputting an output of the 1st transmitter while being fully reflected. CONSTITUTION:The switch 22 in the 2nd transmitter 2 is driven by either the 1st power supply circuit 3 or the 2nd power supply circuit 4. That is, when a fault takes place in the and power supply circuit 4, since the state of full reflection of the switch 22 is produced by driving the 1st power supply circuit 3, the output of the 1st transmitter 2 through a circulator 5 is reflected fully by the switch 22 and sent from a terminal OUT through the circulator 5. As the constitution of the switch 22, e.g., a pin diode is inserted between a line and ground in many cases, and when the diode is turned on, the short-circuit state of the diode causes the output of a modulator 11 to be reflected fully and when the diode is turned off, a high impedance is caused to allow passing. Thus, even if a fault takes place in the 2nd power supply circuit 4, a modulation wave with the specified level is outputted externally.
